How to exclude or include a specific computer from automatic on campuse authentication

You may need to exclude a computer from automatic on campus authentication so that you can test off campus database access from on campus.  This is how it is done:

To exclude a computer from authentication:

• Open the file:  \\eres\alt\datapass.asp
• Save a backup copy.  In case of trouble, just revert back to this saved copy.
• Navigate to this section of code (around line 590)
  •  if (remleft <> "172.18.19") and (remleft <> "172.18.18") then

       tvar = "http://eres.medaille.edu/library/databases/new_database.asp?db=" & thpass

     else

       'here is where you add specific address you want to exclude from authentication

       if (remadd = "172.18.19.56") then

        tvar = "http://eres.medaille.edu/library/databases/new_database.asp?db=" & thpass

      else

         tvar = "http://eres.medaille.edu/library/databases/auth_.asp?db=" & thpass

      end if 

     end if

• Edit the line that says if (remadd = "172.18.19.56)" then to include the IP addresses that you want to add for example:
  • if (remadd = "172.18.19.56") or (remadd = "172.18.19.23") or (remadd = "172.18.19.55") then
• Save the file
• Currently the system is set to exclude any address that starts with 172.18.19 and 172.18.18, all other addresses are included.  You would only need to exclude addresses that are within that range.
• There are some addresses that are listed as being excluded from proxying in the ezproxy.cfg file.  This has no effect on this code, this is actually removing ezproxy from the loop entirely.  With this protocol there is no need to exclude any addresses from ezproxy.
• This computer will now require the user to enter their credentials in order to access the library databases

To include a computer in automatic on campus

• Follow the same steps as above, only remove the IP address from the remadd line, rather than adding it.  This computer will now no longer need to have the user enter their credentials in order to access the library databases.
